Ames testing of direct black 38 parallels carcinogenicity testing

Journal of Applied Toxicology, 1981
AbstractStudies have established that Direct Black 38 and two other benzidine‐based dyes are carcinogenic. The carcinogenic effect has been generally considered attributable to the metabolic release of benzidine from Direct Black 38 and similar dyes. However, Ames tests indicated that when Direct Black 38 is reduced with sodium dithionate it is more ...

Biostatistics of Ames-Test Data

1980
In 1976, Matter stated with regard to the problem of interpreting mutagenicity test results: “Although most environmental compounds can be expected to produce either negative or ‘weak’ effects, there seems to be no scientific work available today that deals with the statistical handling of such results.

Der Ames-Test als Biomarker

HNO, 2001
Hintergrund und Fragestellung. Die Inzidenz maligner Tumoren des Kopf-Hals-Bereichs steigt weltweit an. Hauptrisikofaktoren sind der chronische Tabak- und Alkoholabusus. Durch die Erkennung von Hochrisikopatienten konnen fruhzeitig diagnostizierte Tumoren mit guten Heilungsaussichten behandelt werden.

[Ames test as biomarker].

HNO, 2001
The incidence of squamous cell carcinomas in the upper aerodigestive tract has increased worldwide. The main risk factors are chronic tobacco and alcohol consumption. The detection of high-risk persons is important because early diagnosis of these tumors provides a good chance for permanent healing.

The Salmonella (Ames) Test for Mutagenicity

Current Protocols in Toxicology, 1999
AbstractThe Ames test is a widely accepted short‐term assay for detecting chemicals that induce mutations in the DNA of organisms. The assay is a reverse mutation assay that detects the mutational reversion of his‐dependent Salmonella to his‐independent colonies.

Safranextrakte im Ames-Test

2012
Das Ziel dieser Studie war, den anti-/mutagenen und anti-/oxidativen Effekt der lebensmittelrelevanten Pflanzenteile des „Pannonischen Crocus sativus austriacus“ (Klingenbach/Siegendorf, Bgld) im Ames-Test an zwei verschie-denen Salmonellen-Stämmen (TA98, TA102) gegenüber den Mutagenen TNFone, AFB+S9 und PHiP+S9 zu testen.

Ames mutagenicity tests of overheated brewed coffee

Food and Chemical Toxicology, 1984
Five kinds of coffee samples were prepared from a commercial drip-grind coffee in order to examine the mutagenicity of brewed coffee using the Ames test. The samples prepared were a thick coffee syrup, coffee solid residues, dichloromethane and ethanol extracts of solid residues, a dichloromethane extract of a distillate from normally heated brewed ...

Modified suspension Ames test for testing proteinaceous substances: An initial step

Food and Chemical Toxicology, 1994
The basic Salmonella/microsome assay (Ames test) is a valuable primary tool by which to discriminate mutagens from non-mutagens. For a variety of chemical test substances this test is easily conducted according to international guidelines for genotoxicity testing.
